  • Patent number: 4808061
    Abstract: A backhoe arrangement is disclosed wherein a single dipper arm is adapted for operably, removably engaging a mounting bracket of a tractor mounted, cantilevered type of skip-loader boom arm assembly. The tractor provides support for the cantilevered load by reason that the boom arms are pivoted from a rear end of the tractor while the attached single-arm backhoe is operably deployed to the front of the tractor. The described embodiment provides for significantly reduced weight and complexity, thereby enabling the tractor to be driven during excavating operations. The dipper arm may be swung to positions nearly at right angles to the direction of travel of the tractor.
